[PATCH] Fix find_binary always succeeding

[Seewer Philippe <philippe.seewer-omB+W0Dpw2o@public.gmane.org>]

find_binary inside dracut-functions always succeeds. Independent of 
whether the file actually exists or not.

This patch fixes this.

And since we're using the function not only to find binaries at little 
enhancement there shouldn't be that bad either.
